A semicolon is used to connect two closely related complete sentences, or to separate items in a list when those items already contain commas. It helps make writing clearer without needing a full stop or an extra word like “and” or “but”.

How it works

  • Joining related sentences:
    “I wanted to go for a walk; it started raining.”

  • Separating complex list items:
    “We visited Paris, France; Rome, Italy; and Madrid, Spain.”

Simple rule

Use a semicolon when both sides could stand as separate sentences, but they’re closely connected. It’s stronger than a comma and less final than a period.

Tiny example

“I studied all night; the test was still hard.”
That semicolon shows the two ideas are linked.
